I am having issues locking out my right side during the split jerk and the push jerk. When doing push press I can lock it out but still feel like I have to "grind" through the range". In the video you can see me push jerk it to 95% then grind out the rest of the motion.

Here is a video taken from the back during 9 different singles. In attempt #6, 7, 8, and 9, you can really see what I mean. they can be found half way through the video

The weight goes to about 95% of the way up, then I strict press it out.
